"It has been an absolute delight to work with Heather and A D Practice on their projects. Heather has a great technical knowledge of construction and understands the extra mile needed to see a Passivhaus build through. On multiple occasions, whenever we have needed additional information or to discuss possible changes to the design and she has surpassed all expectations. Look forward to working with both
A D Practice and Heather on many projects in the future."
